8. Make sure the workpiece is supported at all times while sawing. Use a roller stand (not provided) with
larger workpieces if necessary.
9. To properly understand all safety warnings, be familiar with the following safety terms and equipment:
a. Featherboard – A block with "fingers" that hold the workpiece against the fence while sawing.
b. Through-sawing – A cut made from one side of a board to the opposite side, without stopping.
c. Ripcut or Ripping - A cut made parallel to (along with) the grain of the wood.
d. Crosscut or Crosscutting - A cut made perpendicular (at a 90° angle) to the grain of the wood.
e. Push-stick – A narrow strip of wood or other soft material with a notch cut into one end and which is
used to push short pieces of material through saws. It provides a safe distance between the hands and
the cutting tool. Must be narrower than the cut width to prevent contact with the blade.
f. Freehand – Feeding a workpiece through the saw without using a fence or guided support to guide it.
NOT A SAFE METHOD.
g. Kerf – The gap made by the saw in the workpiece.
h. Kickback – A sudden reaction to a pinched, bound, or misaligned blade, causing an uncontrolled wor-
kpiece to lift up and out of the saw toward the operator.
i. Spreader – A metal plate that follows the saw blade to keep the kerf (gap) from closing on the saw blade.
Spreaders, except riving knives, must be aligned to the blade after blade adjustment to prevent binding.
j. Riving Knife – A spreader mounted on the same mechanism as the blade. Generally more effective
than simple spreaders.
10. As noted previously, Kickback is a sudden reaction to a pinched, bound, or misaligned blade, causing
an uncontrolled workpiece to lift up and out of the saw toward the operator. Kickback is usually a result of
tool misuse and can be limited or avoided by following the precautions below:
• Fence must be completely parallel to the saw blade.
• Workpiece must be free from flaws (such as loose knots) and from foreign objects (such as nails and
screws).
• Support large workpieces along their entire length. Large workpieces tend to bend, grabbing the blade.
• Do not use a dull, damaged, or pitch-covered blade.
